Fix some broken conditional forms

Problem reported by Mattias Engdegård in:
https://lists.gnu.org/r/emacs-devel/2020-01/msg00088.html
* lisp/cedet/ede/cpp-root.el (ede-create-lots-of-projects-under-dir):
Remove this quick hack, which didn’t do anything anyway.
* lisp/cedet/ede/pconf.el (ede-proj-configure-test-required-file):
* lisp/emacs-lisp/tabulated-list.el (tabulated-list-print-col):
* lisp/net/nsm.el (nsm-check-tls-connection):
Use ‘when’ rather than bypassing it.  This doesn’t affect behavior
and is better style.
* lisp/cedet/srecode/semantic.el (srecode-semantic-handle-:tag):
Fix typo that suppressed an error.
* lisp/filesets.el (filesets-run-cmd): Fix typo that mishandled spacing.
* lisp/gnus/gnus-cloud.el (gnus-cloud-update-newsrc-data):
Fix typo that caused “GROUP has older different info in the cloud
as of DATE, update it here?” prompt result to always be treated as
“yes”.
* lisp/gnus/mml-smime.el (mml-smime-openssl-encrypt): Simplify,
since smime-encrypt-buffer signals error on failure.
* lisp/international/titdic-cnv.el (tsang-quick-converter): Simplify.
The conversion of this file to utf-8-emacs in
2019-01-08T02:18:40Z!monnier@iro.umontreal.ca removed the
distinction between Big5 and CNS fulltitles in the generated docstring.
* lisp/org/org-agenda.el (org-agenda-show-and-scroll-up):
* lisp/textmodes/table.el (table--generate-source-cell-contents):
Simplify by removing useless code.
* lisp/org/ox-odt.el (org-odt--format-timestamp): Fix typo that
always output time-of-day even when the timestamp lacked it.
